2023-01-06hw/intc: sifive_plic: Update "num-sources" property default valueBin Meng1-1/+7
At present the default value of "num-sources" property is zero, which does not make a lot of sense, as in sifive_plic_realize() we see s->bitfield_words is calculated by: s->bitfield_words = (s->num_sources + 31) >> 5; if the we don't configure "num-sources" property its default value zero makes s->bitfield_words zero too, which isn't true because interrupt source 0 still occupies one word. Let's change the default value to 1 meaning that only interrupt source 0 is supported by default and a sanity check in realize(). While we are here, add a comment to describe the exact meaning of this property that the number should include interrupt source 0.

2023-01-06hw/intc: sifive_plic: Improve robustness of the PLIC config parserBin Meng1-8/+16
At present the PLIC config parser can only handle legal config string like "MS,MS". However if a config string like ",MS,MS,,MS,MS,," is given the parser won't get the correct configuration. This commit improves the config parser to make it more robust.
